A heating tube 17 is fixedly installed on the outer wall of the rotating rod 7 near the material guiding surface 2. The heating tube 17 is spiral-shaped. A temperature sensor 18 is provided on the side wall of the material guiding surface 2. The temperature sensor 18 and the heating tube 17 are electrically connected to the control panel 19 to facilitate heating the raw materials in the storage bin 1 to prevent the raw materials from agglomerating.

[0026] A first connecting rod 9 is fixedly mounted on the outer wall of the rotating rod 7 near the storage bin 1. One end of the first connecting rod 9 is connected to a first scraper 8. A fixed rod 10 is mounted between the outer wall of the first connecting rod 9 near the rotating rod 7 and the first scraper 8. Two first scrapers 8 are symmetrically provided. The ends of the two first scrapers 8 that are away from each other are tightly fitted to the inner wall of the storage bin 1. The other ends of the two first scrapers 8 are fixedly connected to the adjacent first connecting rods 9 to facilitate scraping off the raw materials attached to the inner wall of the storage bin 1. Four fixed rods 10 are provided. The four fixed rods 10 are arranged in pairs and arranged in an X shape.
